SPI_Lcd8_Config

sub procedure SPI_Lcd8_Config(dim DeviceAddress as byte)

Description Initializes the Lcd module via SPI interface.
Parameters - 

DeviceAddress

: SPI expander hardware address, see schematic at the bottom of this page 

Nothing.

Global variables: 

- 

SPExpanderCS

: Chip Select line 

- 

SPExpanderRST

: Reset line 

- 

SPExpanderCS_Direction

: Direction of the Chip Select pin 

- 

SPExpanderRST_Direction

: Direction of the Reset pin 

must be defined before using this function. 

The SPI module needs to be initialized. See SPIx_Init and SPIx_Init_Advanced routines. 

dim SPExpanderRST as sbit at LATF0_bit

    SPExpanderCS  as sbit at LATF1_bit

    SPExpanderRST_Direction as sbit at TRISF0_bit

    SPExpanderCS_Direction  as sbit at TRISF1_bit

...

SPI1_Init()                           ‘ Initialize SPI interface

SPI_Lcd8_Config(0)                     ‘ Intialize Lcd in 8bit mode via spi

None.

SPI_Lcd8_Out

sub  procedure  SPI_Lcd8_Out(dim  row,  column  as  byte,  dim  byref  text  as 

string)

Description Prints text on Lcd starting from specified position. Both string variables and literals can be passed as 

a text.

Parameters - 

row

: starting position row number 

- 

column

: starting position column number 

- 

text

: text to be written 

Nothing.

Lcd needs to be initialized for SPI communication, see SPI_Lcd8_Config routine.
